Vehicle wheel suspension

Abstract

A wheel suspension unit for a motor vehicle having a longitudinal link, having a first end for pivotable vehicle-side connection, a second end for connection to a wheel carrier, and a blade-like link portion resilient in the direction of the transverse axis (Y) and rigid transversely relative thereto. The wheel suspension reduces the number of components by providing a longitudinal link having a resilient portion resilient toward the longitudinal axis (X), wherein the longitudinal link is at least partially produced from a fiber-reinforced plastics material.

What is claimed is: 
     
       1. A wheel suspension unit for a motor vehicle comprising:
 a longitudinal link having a first end for pivotable vehicle-side connection, a second end for connection to a wheel carrier, and a blade-like link portion resilient in a direction of a transverse axis and rigid transversely relative thereto; and 
 said longitudinal link has a resilient portion resilient in a direction of a longitudinal axis, wherein the longitudinal link is at least partially produced from a fiber-reinforced plastics material wherein said resilient portion is constructed in a planar manner and extends parallel with a Y-Z axis plane and said blade-like link portion is constructed in a planar manner and extends parallel with a X-Z axis plane. 
 
     
     
       2. The wheel suspension unit of  claim 1  wherein between said resilient portion and said blade-like link portion there is formed a planar transition portion turned in a helix-like manner and extending adjacent to said resilient portion and parallel with said Y-Z axis plane and extends adjacent to the blade-like link portion parallel with said X-Z axis plane. 
     
     
       3. The wheel suspension unit of  claim 1  wherein said longitudinal link has at said first end a non-resilient bearing for vehicle-side connection. 
     
     
       4. The wheel suspension unit of  claim 3  wherein the non-resilient bearing is at least partially formed integrally with said resilient portion. 
     
     
       5. The wheel suspension unit of  claim 1  wherein a wheel carrier is constructed integrally with said longitudinal link and said longitudinal link merges at the second end into said wheel carrier. 
     
     
       6. A wheel suspension comprising:
 a longitudinal link formed of a fiber-reinforced material having a first end and a second end; and 
 said longitudinal link including a blade-like link portion resilient in a transverse axis and rigid in a longitudinal axis and a resilient portion resilient in said longitudinal axis and rigid in said transverse axis wherein the resilient portion is substantially planar and extends parallel with a transverse and vertical axis plane and the blade-like link portion is substantially planar and extends parallel with a longitudinal and vertical axis plane. 
 
     
     
       7. The wheel suspension of  claim 6  including said resilient portion arranged adjacent to said first end and said blade-like portion arranged adjacent to a second end, said second end adjacent a wheel carrier. 
     
     
       8. The wheel suspension of  claim 6  including a planar transition portion curved in a helix and extending between the resilient portion and the blade-like link portion. 
     
     
       9. The wheel suspension of  claim 6  including a wheel carrier forming an integral portion of the longitudinal link adjacent said second end. 
     
     
       10. A wheel suspension comprising:
 a longitudinal link formed of a fiber-reinforced material having a first end and a second end; 
 said longitudinal link including a blade-like link portion resilient in a transverse axis and rigid in a longitudinal axis and a resilient portion resilient in said longitudinal axis and rigid in said transverse axis; 
 a planar transition portion curved in a helix and extending between the resilient portion and the blade-like link portion; 
 a non-resilient bearing integrally connected to said resilient portion at said first end; and 
 a wheel carrier integrally connected to said blade-like portion at said second end.
